Link object from another blend file that is not positioned at origin
If you link an object, all properties of the object are in the file from wich you linked the object.(inclusive the position)If you want to keep your object movable, you can link the mesh(not the Mesh Object) of the object. Then create a new mesh-object, go to the object-Settings() of the object in the properties window and change the Mesh() to the linked Mesh.
